The “Output Hold/Reset on Communication Failure” flag is set at Bit X2 of Item XTS (RI.69).

X2 = 0 Output reset upon communication failure

X2 = 1 Output hold upon communication failure

When communication fails for the period set in this Item, the XT-9100 goes into “communication failure” state, indicated by a blinking power LED on the front of the module. The default value is 60 seconds.

First configure an XT Module. Select XTn, then Analog or Digital. Then select the just configured XTn, XTn, and Data. At the “Comm. timeout (sec)” field, enter the value in seconds.

The “Maximum Time Between Communications” (in seconds) is entered at Item MTBC (RI.86).

The operational mode of the XT-9100 can be seen at Item OPMO (RI.01) with following status bits:

X8 = 1 PWR Power Failure. This bit is set when a XT is powered up or when there is a serial interface communication failure.

The setting in Item XTS (RI.69) Bit X2 (“Output Hold/Reset on Communication Failure” flag) is repeated in Item OPMO (RI.01) Bit X7 so that it can be read by the DX-9100 or any other monitoring system.

In order to download the XT-9100 devices it is necessary to enter the XT addresses. These addresses will also be loaded into the DX-9100. When performing a download through a DX-9100 Controller, the controller only downloads the addresses of its own XT set. The

XT address is not stored in the XT-9100 but must be set on the address switches on the module.

First configure an XT Module. Select XTn, then Analog or Digital. Then select the just configured XTn, XTn, and Data. At the “Hardware Address” field, enter the address (1-255) of the XT-9100 module.
